4-Amino-1H-1,2,4-triazol-1-ium nitrate

Abstract

The non-centrosymmetric crystal structure of the novel semi-organic title compound, C2H5N4+·NO3−, is based on alternating layers of 4-amino-1H-1,2,4-triazolinium cations (formed by parallel chains of cations mediated by weak C—H...N hydrogen bonds) and nitrate anions interconnected via linear and bifurcated N—H...O hydrogen bonds and weak C—H...O hydrogen bonds. N—H...N hydrogen bonds link the anions and cations.
